Graph this piecewise function:

Pepsi [2]

Consider the function f(x<span>) = 2 x + 1. We recognize the equation y = 2 x + 1 as the Slope-Intercept form of the equation of a line with slope 2 and y-intercept (0,1). Think of a point moving on the </span>graph<span> of f. As the point moves toward the right it rises.

the population of woodstock, Ga is about 23,896 people,and the city encompasses 11.3 square miles. What is the population densit

aev [14]

The population density of Woodstock is 2114.7 people per square mile

Step-by-step explanation:

Population density is the number of people per square kilometer or per square mile

Given

Number of people = 23896

Area = 11.3 square miles

The population density is given by the formula:

$Population\ density=\frac{Number of People}{Area}\\=\frac{23896}{11.3}\\=2114.69=>2114.7\ people\ per\ square\ mile$

Hence,

The population density of Woodstock is 2114.7 people per square mile

Determine the solution to f(x) = g(x) using the following system of equations: f(x) = 3x + 12 g(x) = -9.5x - 13

Anit [1.1K]

Answer:

x=2

Step by step:
f(x)=g(x)

3x+12= -9.5x-13 simplifies to the equation below

3x+9.5x= -13-12

12.5x= -25
next, divide by 12 on both sides to isolate the variable, x.

12.5x/12 = -25/12

x=-2

to check: 3(-2)+12= -95x(-2)-13
-6+12= 19-13
6=6 ✅

Can you think of any 2x2 matrices d for which cd = dc for all 2x2 matrices c? give 2 different examples of such matricesd.

Ksju [112]

For any arbitrary 2x2 matrices $\mathbf C$ and $\mathbf D$ , only one choice of $\mathbf D$ exists to satisfy $\mathbf{CD}=\mathbf{DC}$ , which is the identity matrix.

There is no other matrix that would work unless we place some more restrictions on $\mathbf C$ . One such restriction would be to ensure that $\mathbf C$ is not singular, or its determinant is non-zero. Then this matrix has an inverse, and taking $\mathbf D=\mathbf C^{-1}$ we'd get equality.
